  • Patent number: 9954385
    Abstract: A computing device includes a charging coil for producing a charging current when placed in a magnetic field of a wireless power transmitter. A wireless charging operating frequency is associated with wireless charging of a battery of the computing device by the charging coil and the wireless power transmitter. An electrically conductive substrate has a plurality of gaps for reducing eddy currents when the electrically conductive substrate is disposed between the charging coil and the wireless power transmitter during charging of the battery. A plurality of filters each electrically bridge a respective one of the gaps. Each filter attenuates signals within a range of frequencies including the wireless charging operating frequency.

  • Publication number: 20160380454
    Abstract: In one example a charging sleeve for an electronic device comprises a frame to receive the electronic device and a cover slidably engaged with the frame and comprising a first section connected to a first edge of the frame, a second section connected to the first section by a first foldable joint, a third section connected to the second section by a second foldable joint, and a fourth section connected to the third section by a third foldable joint. Other examples may be described.

  • Patent number: 7654758
    Abstract: In one embodiment, a system and method pertain to measuring the length of media using a first sensing system of the printing device to obtain a first length value, measuring the length of the media using a second sensing system of the printing device to obtain a second length value, and calculating a scale factor that can be applied to measurements made by the first sensing system to increase the accuracy of those measurements, wherein the scale factor is calculated relative to the first and second length values.

  • Patent number: 6678162
    Abstract: An interlock enables power to a computer component to be disconnected prior to removal of the component from an access port. Actuation of a latch enables an operator to move the interlock away from the access port of a computer housing. Movement of the interlock away from a computer housing removes communication of the interlock with a power switch of the associated access port and thereby removes power to the associated access port. In addition, movement of the interlock away from the housing enables an operator to remove and/or place a component in the access port. Similarly, proper placement of the interlock in front of the access port places the interlock in communication with a power switch of the associated access port and provides power to the associated access port, and prevents actuation of an ejection lever of the access port.

  • Patent number: 4725244
    Abstract: A system for assembling electronic work stations including multiple electronic units. The electronic units are provided as subassemblies, premounted into specially formed trays. Special slide engaging male and female mounting components have one of the components formed into the chassis and the other component formed into the tray. The subassemblies are simply slid into place and various locking means are automatically engaged as the subassemblies are forced into their "home" position. The assembly time is greatly reduced resulting in substantial savings.
